Die fatalen Folgen der Implementierung einer HL7-ADT-Schnittstelle

Abstract

The fatal consequences of implementing a HL7 ADT interface One of our sites implemented a HL7 ADT interface for demographic patient data between the hospital information system (HIS) and the radiology information system (RIS). In the RIS, they implemented a rule that merges patient records if these have an identical patient identification number (PID). They didn’t realise that the two systems had overlapping number ranges. As a result, they performed many merges on different patients. Following the RIS, the picture archiving and communication system (PACS) also merged the patient dossiers and changed the corresponding DICOM-header. When the mistake was discovered, we managed to separate the patients in the RIS but not in the PACS. This implicates some decisions and workarounds for the daily tasks of our radiologists and for the future migration to a new RIS/PACS.
